Which version of Tsuna??? The beast who was busting an Island against Daemon Spade with Enmas powers as well, or the chimp who's getting his butt whipped by his dad?
Shell Bullet Ultimate! Tsuna can do nothing to stop him esp. since he can use it on both arms, he's probably faster in flight than Tsuna as well and doesn't have to use he hands to propel himself in flight so more freedom in movements.
I agree, he is actually much faster in flight but he should be able to defeat Tsuna with stage 2 with great ease.
